【考案の詳細な説明】
本考案は、小形直流電動機における中空円筒状回転子に
関するものである。[Detailed Description of the Invention] The present invention relates to a hollow cylindrical rotor for a small DC motor.
従来、中空円筒状回転子において、特に、予め整形して
なる３個の回転子コイル片を外周部に凹部を有したコイ
ル支持枠に挿入固定した中空円筒状回転子では、回転子
コイル片の位置していない部分が存在するため、この部
分で重量のアンバランスが生し易いものであった。Conventionally, in a hollow cylindrical rotor, particularly in a hollow cylindrical rotor in which three rotor coil pieces formed in advance are inserted and fixed into a coil support frame having a recessed portion on the outer periphery, the rotor coil pieces are Since there are parts that are not located, weight imbalance tends to occur in these parts.
またコイルは巻線整形されるが、軸方向の均一な整形は
できず、軸方向のアンバランスが生じ易いものであった
。Further, although the coil is wound and shaped, uniform shaping in the axial direction is not possible, and axial imbalance is likely to occur.
本考案は上記従来の欠点を解消するものであり、その目
的とするところは、前記中空円筒状回転子のバランスを

。The present invention solves the above-mentioned conventional drawbacks, and its purpose is to balance the hollow cylindrical rotor and provide a small DC motor with good performance.
以下、本考案の一実施例について、図とともに説明する
。Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

ンス調整部材６を設置している。FIG. 1 shows a coil support frame 1 having a coil support recess and a commutator 2 fixed to a rotor shaft 3, and three rotor coil pieces formed in advance in the coil support recess. A part of each coil end of 4-1.4-2.4-3 is inserted and fixed from the rotor axial direction, and each coil end part in the direction opposite to the commutator side is inserted and fixed into the support frame 5. This figure shows a hollow cylindrical rotor of a small DC motor, and in this figure, in order to maintain the dynamic balance of the rotor, the spaces between adjacent rotor coils 4-1 to 4-
Balance adjustment members 6 having an H-shaped cross section are installed at 2, 4-2 to 4-3, and 4-3 to 4-1.
このバランス調整部材６は、回転子コイル片４−１．４
−２．４−３をコイル支持枠１に挿入する際に取り付け
、回転子組立て後は、回転子軸方向に自在に移動できる
ようにし、バランス調整後はその位置で固定するもので
ある。This balance adjustment member 6 includes rotor coil pieces 4-1.4.
-2.4-3 is attached when inserted into the coil support frame 1, and after the rotor is assembled, it can be moved freely in the rotor axial direction, and after balance adjustment, it is fixed at that position.
またバランス調整部材６としては金属片でも可能である
が、絶縁および重量から金属粉を樹脂で成形したものが
好ましい。The balance adjustment member 6 may be made of a metal piece, but it is preferably made of metal powder molded with resin for insulation and weight reasons.
さらに厚みとしては、中空円筒状回転子のコイル片の厚

置で固定することにより、可能である。Furthermore, the thickness must be less than the thickness of the coil pieces of the hollow cylindrical rotor, and there are restrictions on the shape, but by measuring the approximate amount of unbalance of the rotor in advance, The material of the metal powder can be determined, and the balance of the rotor can be adjusted by appropriately moving this balance adjustment member 6 in the rotor axial direction, achieving balance, and then fixing it at that position. be.
なお、第２図は第１図の回転子にバランス調整部材６を
取り付けた部分の拡大断面図である。Note that FIG. 2 is an enlarged sectional view of a portion of the rotor shown in FIG. 1 in which the balance adjustment member 6 is attached.
以上のように、本考案によれば、この種の回転子におい
て、重量のアンバランスが生じ易い部分でのバランスの
調節は非常に簡単でしかもずみやかに行なうことができ
、工程の簡単化、時間短縮につながり、その産業的価値
は犬である。As described above, according to the present invention, in this type of rotor, it is possible to adjust the balance in areas where weight imbalance is likely to occur very easily and quickly, which simplifies the process. , leading to time savings, and its industrial value is dog.
